car: 1990 camaro tpi was a 305 , now a 350. 700R trans. 2.73 rear.
I have a thud noise coming out from under my car and it all started one day when i tried to do a burn out and i heard a loud bang. now everytime i step on it the car makes a loud thud, If i pick up slow nothing happens. So i either think its the driveshaft,rear,trans,or a moter mount, but i want to narrow it down, I don't want to change all of them, all help would be great, THANKS to everyone!!

Tranny mounts on these cars break all the time. Get a polyurethane one, it'll last longer.

i had the same problem the first year i got my car. Every time I would take off quick I would hear it. I went with a friend and he checked the tranny mount and it was in half. that year i broke two tranny mounts. Thats probably your problem.

i looked under the car and the nut on the tranny mount was missing, got a new nut and put it on, car feels sooo much better

J isn't kidding..get a Poly mount from Energy Suspension or whoever else you can get it from. A stock piece will just rip again if you keep driving the way you do(normal or aggressive)...Mine ripped a week after I got the car

Note that the poly mount will transmit vibration more so, if you don't mind, go for it. If you do, stick with OEM.
